Order the following statements to correctly describe the route of secreted protein as it is synthesized and secreted from a eukaryotic cell.1. Translation begins on a ribosome.2. The ribosome attaches to the rough endoplasmic reticulum and the newly formed polypeptide is pushed into the lumen of the rough ER.3. The protein folds and undergoes modification within the rough ER.4. The protein travels within a membranous vesicle from the ER to the cis face of the Golgi apparatus.5. The protein travels toward the trans face of the Golgi, from which it is packaged into a secretory vesicle.6. The secretory vesicle travels to and merges with the cell membrane, releasing its contents outside of the cell.
